Hello everyone I posted about wondering if dd2 has a lactose intolerance and it turned out she had tonsillitis . I have posted about this before but she seems to have an incredibly weak immune system in addition to her autism . Since October she has been constantly ill with chest infections, flu , vomiting and now tonsillitis with vomiting . Has anyone any experience of an immunologist and if there is anything that can be done to help as I am going out of my head with worry
